It's the combination: big idea with a good entrepreneur: there's nothing more powerful.

A fundamental American question is, 'What's the big idea?'

If I'm in the country, my big idea is to do nothing. It means talking, it means cooking with the leftovers in the fridge - l'art d'accommoder les restes - it means gardening.

Their lives are bigger than any big idea

I always have a big idea. It pops up every two to three years.

America needs a big idea that plays to its strength. It should look to national service.
